LINUX_SDK COMPILATION

SDK (Software Development Kit) is a set of development tools provided for a specific software framework, hardware platform, or operating system, aimed at helping developers create applications more efficiently.

Compilation Environment Setup

Install Ubuntu 22.04 on a PC for SDK compilation.

• Hardware: PC with RAM ≥ 16 GB, CPU cores ≥ 4, Hard Drive ≥ 500GB
• Software: Ubuntu 22.04, virtual machine disk space allocation ≥ 200GB

Configuration Installation:

Tip

If errors occur during dependency installation, search for the corresponding dependency packages based on the error messages.

Obtaining the SDK Source Code

Note

1. The SDK must not be compiled in a shared directory.
   
2. The compilation host must not be logged in as the ROOT user.

1. Click to download the Linux SDK source code and release_sdk.sh script. Typically, download the latest file with the most recent date suffix.

2. Place the tar.gz package, md5sum file, and release_sdk.sh file in the same directory on the compilation host.

a733-linux-*.tar.gz
a733-linux-*.md5sum
release_sdk.sh

3. Run the script to extract the SDK source code.

chmod +x ./release_sdk.sh
./release_sdk.sh

Illustration

Full Compilation

Tip

Currently, the A733 Linux SDK source code only maintains the Debian 11 system.

1. Enter the SDK source code root directory and execute the following command to configure the compilation target.

./build.sh lunch

Select the configuration file.

a733-linux$ ./build.sh lunch
All available ic:
   0. a733
Choice [0]: 0
All available board configurations:
   0. BoardConfig-a733-kickpi-k10b-debian11.mk
Choice [0]: 0

2. Compile the complete image.

./build.sh 

Separate Compilation

The SDK supports compiling individual modules such as the kernel, modules, device tree, U-Boot, rootfs, etc., without needing a full recompilation each time.

Tip

Before separate compilation, you must first run ./build.sh lunch to select the board configuration.

Command	Description
./build.sh kernel	Compile the kernel
./build.sh modules	Compile kernel modules
./build.sh dtb	Compile the device tree
./build.sh bootimg	Compile boot.img
./build.sh brandy	Compile U-Boot
./build.sh bootloader	Same as above
./build.sh debian_rootfs	Compile Debian root filesystem
./build.sh rootfs	Compile rootfs (generic)
./build.sh arisc	Compile ARISC coprocessor firmware
./build.sh menuconfig	Kernel configuration menu
./build.sh uboot_menuconfig	U-Boot configuration menu
./build.sh pack	Package the firmware
./build.sh pack_debug	Package debug firmware
./build.sh clean	Clean compilation artifacts
./build.sh distclean	Deep clean
./build.sh all-lcd	Iterate through all LCD configurations and compile sequentially (kernel + packaging)
